A woman accused of murdering her husband with a drug overdose as revenge for killing her boyfriend is scheduled to go to trial this summer.

Kelly Marie Cochran, 35, pleaded not guilty at a formal appearance Wednesday morning in Lake Superior Court on a murder charge stemming from the death of her husband, Jason Cochran, two years ago in Hobart.

Prosecutors claim Cochran gave her husband a fatal overdose of heroin Feb. 20, 2016, and put her hands on his neck, nose and mouth until he died, according to court records.

Cochran, who wore a green jail uniform with glasses and her hair in a bun, had a slight smile as Judge Salvador Vasquez set her upcoming hearing dates.

Thomas Vanes, who filled in for Cochran's court-appointed public defender, Derla Gross, on Wednesday, said Cochran may seek a speedy trial.

Vasquez scheduled her for trial on July 9. She was then led out of the courtroom, shuffling in her jail-issued sandals as she walked, and was ordered to appear in court again for a hearing April 11.

When interviewed by investigators, Cochran said she had "evened the score" by killing her husband because he took "the only good thing I had in my life," according to court records.

Cochran was booked in the Lake County Jail last week after from the Women's Huron Valley Correctional Facility in Ypsilanti, Mich., where she is already serving a life sentence without the possibility of parole.

An Iron County, Mich., jury convicted Cochran in May of murder in the death of her boyfriend and co-worker, Christopher Regan, according to court records.

During her trial in Michigan, Cochran testified that she and her husband were soulmates during their honeymoon and "finished each other's sentences."

But the relationship devolved into verbal abuse and physical threats, she testified, adding that her husband threatened "he'd kill me if I ever wanted a divorce."

The couple moved to Michigan in January 2014, and "things were getting rough at home," Kelly Cochran said on the stand in her Michigan trial. Jealousy between them was getting worse, and she had affairs with other men, including Regan, she testified.

Prosecutors alleged Kelly and Jason Cochran had made a pact on their wedding night that if one of them were unfaithful, they'd have to kill their lover.

Cochran, however, claimed during her trial in Michigan that there was no definite pact, and she "didn't take it seriously."

"I thought it was a joke," she said.

Nevertheless, in 2014, Cochran lured Regan to her home in Michigan with the offer of sex when Jason Cochran interrupted them and shot Regan, according to court records.

Kelly Cochran said she got the cord for an electric saw so her husband could dismember Regan's body, put it in garbage bags and dumped it in the woods in northern Michigan, court documents state.

Jason Cochran died two years ago in Hobart, and a recording of a 911 call Kelly Cochran made the day of her husband's death, which the Post-Tribune obtained in response to a public records request, included her pleas for help.
